Abstract: An electrooptic directional coupler (2') having first and second electrodes (22A', 24A'; 22B', 24B') for influencing coupling between a segment of a first optical waveguide and a segment of a second optical waveguide, is operated by varying the potential of the first electrode relative to the second electrode during a first interval in accordance with a first function such that the first electrode remains at a first polarity relative to the second electrode, and varying the potential of the first electrode relative to the second electrode during a second interval in accordance with a second function such that the first electrode remains at a second polarity, opposite the first polarity, relative to the second electrode. The integral with respect to time over the first and second intervals of the potential of the first electrode relative to the second electrode is essentially zero.

Abstract: A road surface friction coefficient estimating method and apparatus in an anti-lock control device for preventing locking of vehicle wheels during braking. The a road surface friction coefficient is estimated by comparing a deceleration of an estimated vehicle speed with a predetermined threshold value. The predetermined threshold value has different road surface friction coefficient values corresponding to different vehicle deceleration values. The braking hydraulic pressure is then repeatedly varied in accordance with signals indicative of the estimated road surface friction coefficient, signals indicative of the estimated vehicle speed, and one of the signals indicative of the slowest rear wheel speed and the front wheel speeds.

Abstract: An object of this invention is to provide an optical shutter-camera which has good resolution and sensitivity. A first optical image forming unit comprises a first optical lens for causing rays from a subject to form a first optical image, and a deflection member for causing the rays from the subject through the first optical lens to form an image by way of an angle adjusting lens. A shuttering unit comprises a variable intensity-pumping beam source for restricting a radiation area including the first optical image, a deflection member, and a ray blocking plate with an aperture disposed on paths of the rays from the deflection member. A second optical image forming unit comprises a second optical lens for forming the first optical image on an output surface. In this structure, an image can be formed on a deflection center of the deflection member. Consequently the image rays can be scanned transversely of the aperture of the ray blocking plate, whereby the shuttering is conducted, and more unblurred stationary images can be formed on the output surface by the second optical lens.

Abstract: A cellular switching system and architecture is described in which the switching associated with a call originated within one cell (e.g.101) but now serviced within another cell (e.g. 102) is distributed among base stations which are interronnected with each other through a local area network (112). The routing procedure associated with the point of origin for a given call is stored in the memory of a switch of public switched telephone network. As an active subscriber crosses a cell boundary, the switch routes all packets of information for the given call to the originating base station for the duration of the call. Each base station then forwards each packet to the subscriber's current base station via the local area network (112). In this manner, the architecture is unaffected by the increased crossing between cell boundaries since the switching associated with those calls not within the range of the initial base station is handled in a distributed manner by each base station via the local area network.

Abstract: A resonant type switching power source implementing zero voltage switching on the basis of the resonance between an inductor and a capacitor. A main switch is connected to the primary side of a main transformer. A pulse width control circuit generates a control signal for varying the turn-on time of the main switch until the output voltage of the secondary side of the tranformer being fed back reaches a predetermined value. A resonance capacitor is connected in parallel with the main witch. When the terminal voltage of the capacitor crosses zero potential toward the negative side, the pulse width control circuit delivers an ON command to the main switch. Alternatively, the ON control over the main switch may begin at a time a predetermined period of time later than the time for turning on the resonant circuit.

Abstract: An information processing network (16) includes multiple processing devices (18, 20, 22, 24), a main storage memory (28), one or more disk drives (30) or other auxiliary storage devices, and an interface (26) for coupling the processing devices to the main storage memory and the auxiliary devices. A primary directory (124) in main storage contains mapping information for translating virtual addresses to real addresses in main storage. Look-aside buffers (24, 82, 84, 86) in the processing devices duplicate some of the mapping information. A primary directory hardware lock, subject to exclusive control by any one of the processing devices to update the primary directory, inhibits access to the primary directory based on hardware address translations initiated when one of the processors holds the primary directory lock. Address translations in progress when the lock is acquired proceed to completion before the primary directory is updated under the lock. Accordingly, such updates proceed atomically relative to hardware primary directory searches. Unnecessary quiesces and purges of the look-aside buffers are eliminated, substantially improving network performance.

Abstract: Crankshaft, in particular for a five-cylinder in-line engine, in which there are five successive offsets in the direction of the crankshaft axis, in the sequence 1, 4, 3, 2, 5, 1 and 5 representing the two outer offsets, 2 and 4 representing the two inner offsets and 3 representing the central offset, and in which the offsets 1, 2, 3, 4, 5 enclose unequal (non uniform) angles between them. Complete balancing of the inertia forces and first-order moments of inertia is achieved by virtue of the fact that the angle of each of the two inner offsets 2 and 4 relative to the central offset 3 is smaller by a small angle  alpha  than 72 DEG  and that the angle of each of the two outer offsets 1 and 5 relative to the central offset 3 is larger by a second small angle  beta  than 144 DEG .

In the method for producing the flat-tube heat exchanger (12) with intermediately reinforced flat tubes (12), the ends of the flat tubes (12) which are inserted into the slots of an accumulator are cut free from their intermediate reinforcement (42) and widened towards the slot circumference of the accumulator. The applications of the heat exchanger relate to use as condenser of a vehicle air-conditioning system or the cooler for engine, transmission or hydraulic oil in a motor vehicle. Flat tubes for fitting in the flat-tube heat exchanger are concatenated.

Abstract: Local interconnect is defined in a polycrystalline silicon layer. Openings to underlying conducting regions are made through an insulating layer after the local interconnect conductor definition. A thin extra polycrystalline silicon layer is then deposited over the device and etched back to form polycrystalline silicon sidewall elements. These sidewalls connect the polycrystalline silicon local interconnect conductors to the underlying conductive regions. Standard silicidation techniques are then used to form a refractory metal silicide on the exposed underlying conductive regions, the polycrystalline silicon sidewall elements, and the polycrystalline silicon local interconnect conductors. This results in a complete silicided connection between features connected by the local interconnect conductors.
